These patches provide support to read different watchdog device status
through sysfs interface.
Changes since V4:
* All sysfs code has been protected under CONFIG_WATCHDOG_SYSFS
Changes since V3:
* Added Reviewed by tag
* Corrected a checkpatch warning
Changes since V2:
* Used static struct class watchdog_class in stead of pointer. It helped to
keep using device_create().
* Above logic was moved to a separate patch. Changed subject line of other
patch to look more relevant
Changes since V1(RFC):
* Removed keepalive and start ABI
* timeout is read only now
* state returns text
* only supported ABI visible
* ABI contact changed to MAINTAINER
* unnecessary mutex removed
* aligned continuation with '('
* unnecessary initialization of status (= 0) corrected
* unnecessary else removed
* used __ATTRIBUTE_GROUPS
* removed watchdog_device_create and added functionality in
* watchdog_dev_register.
* optimized nowayout_show
* Now no -EOPNOTSUPP return for timeout read in case of
* wdd->timeout = 0.
